Portland Cement and Masonry

Testing characteristics of hydraulic Portland Cements and grouts assures predictable performance in final mix batches of concrete and masonry products. Gilson offers a wide selection of products for testing strength, shrinkage rate, consistency and flowability, hydration, set time and other properties of cement and similar materials in accordance with ASTM and AASHTO standards.

Cube Molds are available constructed of plastic or different metals to form cube specimens of 2x2in, 6x6in or ISO 150x150mm; many meeting ASTM and AASHTO standards.

Prism Molds in single or two-gang configuration are made of corrosion resistant steel or stainless steel to form 1x1x10in, 2x2x10in or 3x3x10 prisms. Each model meets ASTM C227, ASTM C151, ASTM C490, AASHTO T 107M and AASHTO R 70 standards.

Grout Sample Box is specially designed to form samples, store and ship. The Grout Sample Box is single use, and sets up easily for molding samples for testing.

Trowels with straight or curved edges are convenient for mixing/handling of samples and meet ASTM and AASHTO standards. The straight-edged trowel meets ASTM standards for proper consolidation and strike off of mortar and grout specimens.

Vicat Apparatus is used to determine consistency and time of set of cement paste and other similar materials, Vicat Apparatus is also available in a modified model for determination of false set.

Mortar Penetrometers available in a free-standing floor model or hand-held, both styles are ideal for testing prepared mortars and grouts in field and laboratory settings for initial and final set times.

Gillmore Needle Apparatus determines initial and final set times of certain cements, mortars and hydraulic hydrated lime.

Flow Tables used for determining flow consistency of mortars, Flow Tables have a 10in rigid cast bronze table and cast iron frame. They are available in both a manual and motorized style.

Grout Flow Cone Sets measure flowability of hydraulic grout in preplaced aggregate concrete as determined by time of discharge through an orifice. Available in two models – one with a larger orifice for thick grouts.

Fineness Test Apparatus meet standards for particle sizing of fine materials such as Portland and other hydraulic cements, fly ash, and other materials that require a constant-pressure water wash in testing.

ASTM Test Sands for specific test methods are available in a range of compositions and grades, and meet specific ASTM and AASHTO standards.

Laboratory Cement Mortar Mixers with two models of industrial-grade Laboratory Mixers, Planetary and Large Planetary, that meet ASTM and AASHTO specification requirements for consistent, thorough blending of mortar, cement and other materials.

Blaine Air Permeability Apparatus used to measure specific surface area and determine air flow rate through fine powder specimens, such as Portland cement. This apparatus meets AASHTO T 153 and ASTM C204 standards.

Stainless Steel Straightedges are for trimming and leveling concrete and soil specimens. Stainless Steel Straightedges meet many ASTM and AASHTO testing standards. Models available with plain finish or with laser-etched graduations.
